Privacy policy
Olympus OS reads the times and titles of calendar events that a household shares with it. It keeps them on the household's own computers. It never sells them, never shares them, never uses them for advertising, and never sends them to an AI service outside the home.
Effective October 6, 2026. This policy covers Olympus OS, a private system run by Marquis Stafford for his
household, and the Google account it uses (osolympusv3@gmail.com). It isn't offered to anyone else.
What Olympus gets from Google
- Permission: "See your calendars" (
calendar.readonly), granted by Olympus's own Google account. It is the only Google permission Olympus asks for, and it is read-only. - Calendars: only the calendars a household member chooses to share with Olympus's account.
- Fields: the name of each shared calendar, and each event's start time, end time and title, for at most 31 days ahead. Olympus drops descriptions, locations, guest lists and meeting links as soon as Google returns them, and never stores them.
Olympus doesn't use Google to read email, files, contacts or anyone's profile, and it never signs in as a household member.
How it's used
- To put the day's schedule in the morning and evening brief that Olympus prepares for the adults in the household.
- Nothing else. Calendar data isn't used for advertising, isn't used to build profiles, and isn't used to train any AI model, Olympus's own or anyone else's.
- When an AI model reads it, that model runs on the household's own computers. Olympus labels calendar data at its most private level, and its rules refuse to send data at that level to any AI service outside the home.
Where it's kept, and for how long
- At home. Olympus runs on the household's own server, which can't be reached from the internet. What it reads is recorded in its action log there, so the household can see what it did and why.
- Backups. The server is backed up to other computers in the home. An encrypted copy may also be kept with a cloud storage provider, which holds only encrypted data it can't read.
- Access. Only the adults in the household can see Olympus's records. Its Google sign-in is kept as a secret on the server, readable only by Olympus, and is never written to a log.
- How long. Records stay in the action log until the household deletes them. Anyone whose calendar was shared can ask for their data to be deleted, from the log and from the backups as they rotate, at the address below.
Sharing
Olympus doesn't sell, rent or share Google user data with anyone. It doesn't transfer it to any other app or service, except an encrypted backup as described above, or where the law requires it.
Your control
- Stop sharing. Remove Olympus's account from a calendar's sharing settings in Google Calendar, and Olympus can no longer read that calendar.
- Revoke access. The owner of Olympus's Google account can remove Olympus OS at myaccount.google.com/connections, which ends all of its access to Google.
- Ask. To see or delete what Olympus holds about you, write to the address below.
Google API Services User Data Policy
Olympus OS's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Changes
A later version of Olympus is planned to ask Google for two more permissions: to create one calendar of its own and add events to it, and to send email only to the family's own photo frame. It doesn't ask for either today. This policy will be updated, with a new effective date, before it does.
